ABSTRACT:
A multiplexing unit on the transmitting side estimates information amounts supplied from respective signal processing units, determines a multiplex code on the basis of respective information amounts, derives a parity of the first determined multiplex code to form a second multiplex code, adds a CRC to each of the multiplex codes to generate two headers H1and H2, takes out information data of respective media according to the multiplex codes, incorporates the information data into a packet together with the two headers H1and H2, and outputs the packet. If error correction of H1is impossible on the receiving side, error correction decoding is conducted by using the header H2. If error correction of H2is also impossible, error correction decoding is conducted collectively for H1and H2.
